A new survey by VPN provider Surfshark has found that Chrome collects the most information from users’ phones, while “TOR stands out as the most privacy-centric browser by collecting no data at all.”

The two were among 10 that researchers analyzed, after using AppMagic, a market intelligence tool, to select the most popular browser apps on Apple phones in the US in 2025, they said in a post outlining their findings.

The researchers noted, “Chrome is the most data-hungry, collecting 20 different data types across numerous categories. These include contact info, financial details, location, browsing history, search history, user content, identifiers, usage data, diagnostics, and other types of data. Chrome is the only browser that collects financial information, such as payment methods, card numbers, or bank account details.”
